Question type: Mathematical calculation
Solution:
20/1.15+20/1.15^2+1020/1.15^3
=20/1.15+20/1.3225+1020/1.15^3
=20/1.15+20/1.3225+1020/1.520875
=17.391304+20/1.3225+1020/1.520875
=17.391304+15.122873+1020/1.520875
=17.391304+15.122873+670.666557
=32.514177+670.666557
=703.180734
Answer:20/1.15+20/1.15^2+1020/1.15^3=703.180734
